    Ecoply® Barrier provides a weathertight rigid air barrier for drained and vented cavity systems outside the building frame, effectively replacing traditional building wrap in the cavity while providing structural bracing, and forming a strong secondary line of defence against moisture penetration into the building envelope.

    Ecoply Barrier is suitable for use in both residential and commercial buildings and consists of a 7 mm thick H3.2 cca (copper chrome arsenate) water borne treated structural plywood panel which is coated on the face and edges using a polyester powder coating process for increased sheet durability and protection from moisture penetration.

    Ecoply Barrier meets the New Zealand Building code (NZBc) requirements for rigid underlays as outlined in section 9.1.4, the performance requirements of Table 23 of E2/ aS1, and has been tested for wind speeds exceeding Extra High wind zone as defined in NZS 3604. Testing has been completed to provide solutions for buildings outside the scope of NZS 3604. For details on this, please contact cHH Woodproducts for further information.

    The Ecoply Barrier system is BraNZ appraised for use as a rigid sheathing and temporary weather-protecting sheathing on timber framed buildings.

    The Ecoply Barrier system must be competently installed in accordance with good building practices and sound design principles to satisfy the requirements of the Building act 2004, the New Zealand Building code (NZBc), and applicable New Zealand Standards. This is the responsibility of building owners and the design professionals and builders that they engage. This document contains information, limitations, and cautions regarding the properties, handling, installation, usage, and the maintenance of the Ecoply Barrier system. However, to the maximum extent permitted by law, carter Holt Harvey Woodproducts assumes no legal liability to you in relation to this information.

    Ecoply Barrier panels are engineered to allow the wall system to breathe and dry out, while also preventing the intrusion of exterior moisture. once the full system has been installed, the system provides a lasting protective barrier.

    What is a rigid air barrier?

    a rigid air barrier is a barrier against air pressure and water infiltration from the outside to the interior of the building. a rigid air barrier acts as a secondary line of defence against water penetrating into the wall system – the primary defence being the exterior wall cladding.

    Definition of an Air Barrier:

    • impermeable to airflow — the system must be continuous (no holes, openings or penetrations) and resistant to air pressure differentials

    • continuous over the entire building enclosure • able to withstand the forces that may act on them during

    and after construction

    The Ecoply Barrier system is a full sheathing system developed to prevent unwanted air movement and replace traditional building wrap.

    The information contained in this document is current as at September 2015. It is your responsibility to ensure you have the most up to date information available. The information contained in this publication relates specifically to the Ecoply Barrier system manufactured by Carter Holt Harvey Woodproducts and must not be used with any other plywood manufacturer’s products no matter how similar they may appear.

    Alternative plywood products can differ in a number of ways which may not be immediately obvious and substituting them for Ecoply Barrier structural plywood products or Ecoply Barrier tapes is not appropriate, and could in extreme cases lead to premature failure and/or buildings which do not meet the requirements of the New Zealand Building Code (NZBC).

    4.1 ARCHITECTS / DESIGnERS

    Modern construction practices are moving toward providing greater energy efficiency and an airtight building envelope. These principles of high performance building are common in nearly all current green building standards and construction codes. proper sealing between wall assembly components prevents unwanted air movement in and out of conditioned air spaces.

    • Ecoply Barrier can form an integral part of a weathertight system including two of the four ‘Ds’ of weathertightness; drying and drainage

    • a rigid air barrier provides a more robust cavity and prevents the insulation bulging, which would increase the chance of moisture bridging from the cladding to the framing line

    • provides both structure support and protection from moisture. Structural bracing is achieved when installed in accordance with the Ecoply Barrier bracing specifications. Bracing benefits may result in cost savings by reducing internal lining bracing elements (refer to section 7.6 on bracing – pg 15)

    • BraNZ appraised system, fully tested and code compliant rigid air barrier system

    • Manufactured from sustainable plantation pine and available FSc certified (ScS-coc-001316) upon request

    • low formaldehyde emission level (Eo)

    4.2 BuILDERS

    Ecoply Barrier lets you say goodbye to flexible wall underlays forever. Builders no longer have to worry about installing traditional housewrap or building paper on a windy day or having to return for re-work due to rips, tears or wrap that has blown off the home. The Ecoply Barrier system can typically save up to 2-4* weeks off the total house build time*, by allowing a faster building close in, for an earlier interior start and a quicker over
